Information-Theoretically Secure MPC Against Mixed Dynamic Adversaries

In this work we consider information-theoretically secure MPC against an mixed adversary who can corrupt \(t_p\) parties passively, \(t_a\) parties actively, and can make \(t_f\) parties fail-stop. With perfect security, it is known that every function can be computed securely if and only if \(3t_a + 2t_p + t_f < n\), and for statistical security the bound is \(2t_a + 2t_p + t_f < n\).
